The photocatalytic NO-removal activity of g-C3N4 significantly enhanced by the synergistic effect of Pd0 nanoparticles and N vacancies

Abstract

Graphite carbon nitride (g-C3N4) has been proven to have photocatalytic activity for NO-removal under visible-light irradiation. However, the competitive adsorption between NO and O2 during the process may decrease the NO-removal activity of g-C3N4. In this study, N vacancies were constructed around Pd0 nanoparticles through the heat-island effect. The co-existence of N vacancies and Pd0 nanoparticles created a synergistic effect, which weakened the competitive adsorption between NO and O2. Moreover, this synergistic effect improved the charge transfer and produced more hydroxyl radicals. As a result, the NO-removal activity of g-C3N4 was significantly improved. This study provided new insights into the design of photocatalysts used to remove gas pollutants through photocatalysis.
